That's the only one (that I found). GT2, GT3, and GT4 have all been in this forum. I dug into the archives. (Like I said before, I'm just getting started with the WRS.) If no one's continuing to run GT2 or GT3 races, maybe it's because interest has waned, I don't know. I think it would be cool to run some GT2 and GT3 series, go back to Rome Night, Seattle Short, or (God forbid!) SS11. There's nothing in this forum that says GT only, except what everybody thinks of as conventional. If Jordan says we need to take our toys and go play somewhere else, we will, but I don't see the problem.
So even if all 5 games had a race going every week, there would be 5 races. Is it really that hard to find your thread out of 5? I know, I know, you want to go back to previous events. Fine. If you have to find a thread, use the IE menu's Find (on this page). It'll highlight it for you. Automatically. Look at the blue place on the screen.
I see people calling this the GT4 WRS, but it doesn't say that in the title, it says GTPlanet, the name of the site. Nothing about GTPlanet implies "GT4 only" to me.
Is this gonna be a gang war, now? Bikers Vs. Ricers?
I really don't care which way it goes, I see Jordan's point about cluttering up the forum space, and even though it might be better organizationally to separate the TT series, but I don't think it really matters either way. I've never had trouble finding a thread I wanted, but it's more of a hassle if I have to switch forums all the time to do it. I don't like being thought of as an intruder, though. . . . I've been playing GT since GT2, 100% and all gold all the way through. I shouldn't be an intruder.
